Méthode de changement d'échelle globale adaptative - Application aux réservoirs fracturés tridimensionnels

Abstract : Most methods for modeling fractured reservoirs rely on the model of Warren and Root (1963). But this model is limited by: the assumption of a representative elementary volume, the evaluation of matrix-fracture transfers, the idealization of the fractured system, the use of local boundary conditions. The developed method overcomes these four points. A fracture network and a matrix grid are jointly discretized, then an upscaling is carried out. A set of representative nodes is selected, and an equivalent simplified system is built by decimating the other nodes while ensuring the preservation of pressure and flow rate and without imposing any boundary conditions. Finally the number of connexions is reduced and the remaining transmissibilities are evaluated by an optimization procedure. These simplified systems have been solved more quickly by the flow simulator while reproducing the fine model behavior
